Specilcation of'Lettem Patent.

Parental Jau. es, 1909;

To all whom 'it may concern: I

Be it known that I, FRANK B. Trfrnow, a

, citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania., have invented a certain new and useful Improvement in Traveling Fans, of which the following is a specifcation.

My invention relates to a new and useful improvement in traveling fans, and has for its object to provide an exceedingly simple and effective device which will be self impelled upon an electrically charged track.

A further object of my invention is to provide `a fan which lwill'travel'about a room or building thus expelling the foul air from every corner of the room or building.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then .specificallyf designated by the claims.

AIn order that those skilled in the art to which this invention appertains may understand howto make and use the same, l will describe its construction in detail, referring by letter to the accompanying drawing forming` a part of this specification, in which the ligure is a view of a portion of a track showing the fan hanger thereon.

In carrying out my invention as here ein bodied, A and B represent the two rails of an endless track which are supplied with electricity. In the drawing I have shown only a portion of this track with a curve therein and it is obvious that this track may be any length and have many turns therein so that the fan would travel around a .room or around or through different rooms on the same floor of a building.

C indicates a hanger which is secured to the under side of the tracks A and B then curve around and extending upward until they are again brought and held together by means of the insulated join't D. The rod E is fastened to the upper portion by the insulated joint l) and then to the ceiling` of the room and in this manner holding the track in any desired position.

surface.v of theV base Hv and the groove/d wheels J secured to the upper ends-of the hanger rods I, said grooved wheels J being `adapted to run upon the upper surface of the track.

To the'under surface of the base H is secured the fan motor K4 having a shaft L passing throu h and extending beyond the end thereofl o one end of this shaft is secured the small fan M and to the opposite end the large fan N, the blades ofthese fans are of` different pitch and when they are in motion will blow the air in two-'directions and they will also be worked. against one another thus preventingrv the fan from moving tooswiftly along the track.

O indicates the wires one end of which is secured to the fan mot-or the opposite end to two of the hanger rods l thus carrying the electricity to the fan.

Vhen the fans are set iny motion the large one will press against the airv with sutlicient force to impel the device along the track.

In practice the track would be secured by means ofthe hanger to the ceiling of the room or buildingl in which it is to be used and might be so hung as to pass up one side and down the other around a circle or a number of different gracefulcurves.

V-hen the electricity is turned on it will pass through the wires F into the rails A and B forming the track therefrom through the medium of the wheels J the hanger rods l and the wires C) into the fan motor K, this will at once set the fans M and N in motion. The blades of the fan N being larger than those of the fan M would at once start the 'i device travelingl around upon the track in the direction shown by the arrow. The smaller fan M would be working against the larger fan N thus slightly retarding the speed of the device which otherwise would be very great. l

lt will be seen from the foregoing description that the fans will produce. a current of air in the upper portion "of the room in which it is traveling thus expelling the .foul air from the corners or parts of the room in which it travels.4

Of course I do not wish to be limited to the exact details here shown as in place of the two hanger rods I on that side .of the device'which travels around the inside curve of the track one might be used thus producing a pivot point around which the outside llU hanger rods would travel and in this way the device would be able to pass around a Very short curve.

Havin thus fully described my invention, what I c aim as new and useful, is-

l. In combination, an electrically charged track, means for hanging the same to the ceiling, a traveling hanger adapted to move about upon the track, and a fan motor secured .thereto having a large and small 4bladed fan secured to the end thereof, as

and for the purpose set forth.

2. In combination, an endless track, a hanger for securing the track to the ceiling, wires for supplying the tracks with electricity, a traveling hanger composed of a base, hanger rods the lower ends of which are secured to said base and grooved wheels fastened to the upper ends of said hanger rods, and fans secured to the under -side of said base, as shown and described.

3. In combination, an endless track, a hanger for securing the track to the ceiling, wires for supplying the tracks with electricity, a traveling hanger composed of a base, hanger rods the lower ends of which are secured to said base,and grooved wheels fastened to the upper ends of said hanger rods, a fan motor secured to the under side of said base, and fans secured thereto, as and for the purpose set forth.

4. In ,combinatiom an endless track, a

tricity, a travelling hanger composed of a.

fastened to the upper ends of said hanger rods, a fan motor secured to the under side.` of said base, a shaft. running through said' fan motor the ends of which project beyond the ends of said motor, and fans secured to these ends as shown and described.

5. In combination, an endless track, `a hanger for securing the track to the ceiling, wires for supplying the tracks with electricity, a traveling hanger composed of a base, hanger rods the lower ends of which are secured to said base and grooved Wheels fastened to the upper ends of said hanger rods, a fan motor secured to the under side of said base, a shaft running through said fan motor the ends of which project beyond the endsv of said motor, a small fan secured to one end of said shaft, and a -larger fan secured to the `opposite end of said shaft, as shown and described.

In testimony whereof, I have hereunto aHXed my signature in the presence of two subscribing witnesses.
